Laravel 在后端返回数据，但不在前端

Question

我有orders 表并且我将我的订单数据保存在product_name 列中作为json，我可以在管理面板中获取我的订单数据但是当我尝试在前端使用相同的代码也向用户显示订单详细信息时它返回错误。

为 foreach() 提供的参数无效

后端

public function index()
{
  $orders = Order::orderby('id', 'desc')->paginate(10);
  return view('admin.orders.index', compact('orders'));
}

admin index

@foreach($orders as $order)
  {{$order->payment_id}}
  {{$order->total_items()}}
@endforeach

admin edit page（看看我是如何从product_name 专栏获得详细信息的）

public function edit($id, Request $request)
{
  $order = Order::find($id);
  $statuses = Orderstatus::all();
  $addresses = Address::where('user_id', $order->user_id)->get();
  return view('admin.orders.edit', compact('order', 'statuses', 'addresses', 'json'));
}

edit blade

<p>#{{$order->payment_id}}</p>
@foreach($order->product_name as $data)
  {{ $data['name'] }}
  {{$data['quantity']}}
  {{number_format($order->total_price(), 0)}}
@endforeach

前端

public function orders(Request $request)
{
    $orders = Order::where('user_id', '=', Auth::user()->id)->orderby('id', 'desc')->paginate(5);
    return view('front.orders', compact('orders'));
}

in blade

@foreach($orders as $order)
  #{{$order->ordernu}}
  @foreach($order->product_name as $data)
    <li>{{ $data['name']}}</li>
  @endforeach
@endforeach

然后我得到这个错误：

为 foreach() 提供的参数无效

对此有什么想法吗？

更新

dd($orders)结果

为了得到你想要的结果，你需要循环orders.items，因为它是一个分页器对象

foreach($orders.items as $order)
{
  //rest of code
}
